Title: Closure for a container for a liquid, such as a metal beer cask
Inventor: TURNER ERIC CLIFFORD
IPC: B67D1/08
Filed: 1959-03-25
Abstract: 914,091. Taphole valves. WATNEY MANN Ltd. June 24, 1960 [March 25, 1959], No. 10373/59. Class 21.  According to the Complete Specification, a closure for a neck 48 of beer cask or the like has a fixed inner neck portion 41 secured to an enlarged upper end 44 of a withdrawal pipe 45 extending into the cask, and a tubular valve body 52 displaceable in a sleeve 58 against a spring 64, the cask being tapped by forcing an extractor device downwardly against the valve body 52 to cause it to slide through the sleeve 58 to expose an aperture 55 in its side wall, this action permitting liquid to escape via the tubular valve body 52. In this initial setting a lower sealing member 60 on the sleeve 58 is seated by gas pressure against a stationary flange 66 to seal off a gas space between the inner neck portion 41 and the valve body 52 from gas aperture 47 formed in the enlarged upper end 44 of the pipe 45. Further downward movement of the extractor device causes it to engage an upper seal 61 on the sleeve 58 and so force the sleeve 58 downwardly until the lower seal 60 seals against the upper end 44 of the pipe 45. The apertures 47 are then in communication with the gas space between the inner neck portion 41 and the valve body 52. An outer neck portion 42, screwed into the container neck 48 to secure the inner neck and the withdrawal tube in position, has cut-sways 69 to accept a bayonet fitting on the extractor device. The pipe 45 is fitted with a sliding extension piece 67. According to the Provisional Specification the inner neck portion I is screwed on to the enlarged upper end 4 of the withdrawal pipe 5 and gas apertures 10 are formed in the side walls of the inner neck portion. When a nozzle 20 of an extractor device 19 is pushed downwardly against a tubular valve body 11, the body 11 moves through a sleeve 13 against a spring 16, to expose side apertures 20 in the body 11 to the interior of the end 4 on the pipe 5. Liquid can then pass up through the nozzle 20 and out through a rotatably controlled tap 24 actuated by a lever 26. Further downward movement by the extractor device 19, to cause bayonet pins 22 thereon to engage in slots 32 in an outer neck portion 2, causes the nozzle 20 to engage the sleeve 13 and force it downwardly through the inner neck 1 until it engages the enlarged upper end of the withdrawal pipe 5. In this way the valve body 11 is sealed from the perforations 10 and gas can then be forced through a non-return valve 29, thence through a passage 31 and past the outer face of the cylindrical part of the sleeve 13 which now does not seal against the neck 1, and thence out through the aperture 10 in the extractor device 19. Specification 914,092 is referred to,

Title: An improved electrical method of and means for the prevention of corrosion and for the indication of faults in the associated circuits
IPC: G08B25/00
Filed: 1927-04-19
Abstract: 293,909. Cumberland, E. April 19, 1927. Addition to 277,417. Corrosion, preventing.-In the method of preventing corrosion due to electric currents described in the parent Specification, fault-indicating devices are included across the actual or suspected source of the stray currents. A steam condenser 1 is protected from stray currents from the mains 2, 3 by the provision of insulated anodes 8 connected to the positive main 2 by leads 4 - - 7 while the body of the condenser is earthed at 9. Each anode lead includes a lamp 12, and the negative main includes corresponding lamps 11. Fault-indicating lamps 14, 15 are connected across the mains 2, 3, the mid-point 16 being earthed. The lamps 11 are also earthed at 10. The lamps 14, 15 are normally of equal brightness, but a short circuit from either of the mains to earth causes the lamps to be uneqally bright. The lamps 11, 12 act as indicators in a similar manner the event of short-circuits in the leads between the mains and the condenser. The lamps may be replaced by other resistances and other types of indicators may be used.

Title: A method of limiting interruptions of service in electrical transmission and distribution systems, and a construction of fuses therefor
IPC: H01H85/042
Filed: 1931-06-10
Abstract: 389,107. Protective cut-out arrangements. SCHWEITZER & CONRAD, Inc., 4435, Ravenswood Avenue, Chicago, U.S.A. -(Assignees of Conrad, N. J.; 1099, Pelham Road, Winnetka, Illinois, U.S.A.) June 10, 1931, No. 10612. Convention date, July 24, 1930. [Class 38 (v).] A distribution system, such as shown in Fig. 1, having circuits 3, 5, 7, 9 of .successively decreasing power rating is protected by fuses 12 .. 16 which are so correlated as regards their time-overload characteristic that upon the occurrence of a fault those fuses further from the fault will not operate before periods of time greater than required to permit operation of fuses nearer to the fault. In some cases there may also be automatic circuitbreakers also included in the system, for example a step-down transformer may have a fuse located on its high tension side-and a circuit-breaker on the low tension side, in such cases the time-overload characteristic of the fuses is also correlated to that of the circuit breakers. The time-overload characteristic of the.fuse is controlled by varying the length of the fusible element while maintaining the required rated current carrying capacity by appropriate choice of cross-section. In addition, the characteristic may be varied by complete or partial submergence of the element in carbon tetrachloride or granulated cork. The fuses require to be such that when fusion starts, the arc should be extinguished before other fuses start to operate. Several forms of fuses are described, all generally similar to that shown in Fig. 4. A glass sleeve 38 has a ferrule 36 closed by a cap 39, and supports through a spider 74 a fuse terminal 40, to which a fusible link 43 and a strain wire 44 are attached. The lower ends of the link and wire are attached to a terminal 42 which is urged downwards by a spring 45, and supports by means of pins 62 a liquid director 58. A fibre tube 86 is supported by a ring 80 and is secured yieldingly therein by means such as screws 89 and washers 90. Upon rupture of the fuse, the liquid director and terminal 42 are drawn downwards and liquid is forced into .the tube 86. If the pressure generated is sufficient, it is released progressively by forcing off the cap 39, then the spider 74 and then ejecting the tube 86 by rupture of the washers 90. The size and shape of the tube 86 and director 58 may be varied, as also the manner of yieldingly securing the tube 86. The level of the liquid in the sleeve 38 may be adjusted, in some cases it completely surrounds the fusible element, and in some cases the tube 86 or the space above it may be packed with granulated cork.

Title: Improvements in or relating to means for inserting metallic fastenings suitable for use in the manufacture of boots or shoes
IPC: A43D69/04
Filed: 1932-04-18
Abstract: 401,706. Stapling. BRITISH UNITED SHOE MACHINERY CO., Ltd., LANE, H., and PRATT, J. W., Belgrave Road, Leicester. April 18, 1932, Nos. 11021 and 16271. [Class 89 (iii).] Relates to a fastenerinserting machine, such as is described in Specification 294,640, [Class 89 (iii), Nailing &c.], wherein a fastener is caused, during driving, to engage a deflecting member whereby it assumes a bent condition within the work, and consists in detail improvements. The machine shown, as in the aforesaid Specification, comprises a staple-transferring member 31, a driver 1 reciprocated by a spring-loaded lever 7, and a deflecting member 33 formed with grooves which engage and guide the staple legs during driving. The said parts are carried by a slide 11 which has a downward and inward movement, after the shoe upper has been pulled over, to bring the parts to working position. In the present construction, the driver passage along which the staple is driven is arranged to give the whole of the staple adequate support right up to the face of the deflector 33. To this end, the staple-guiding extension on the deflector referred to in the aforesaid Specification is dispensed with, and the lower limbs of the transferring member 31 are widened as at 35 to serve as supports for the upper face of the staple. The driver passage is formed in a solid metal block 41 which cannot yield to distorting thrust on the staple legs. The guiding rib 43, Fig. 3, on the driver 1 is located on the upper, instead of the under, side of the driver. The member 31 and the inside former 32 are respectively notched and shortened to permit this. The driver is retained in its passage by a dove-tailed plate 45 which is retained on the block 41 by a bolted plate 49. The plate 45 is adjustable in the direction of the deflector 33, and its upper face forms a plane support for the under face of the staple. The driver is arranged to be retracted slightly when the slide 11 moves away from the work, to prevent fouling of the head of a staple which has not been properly driven. To this end, upward, driving, movement of the lever 15 which actuates the lever 7 is limited by an abutment 57 adjustable on a fixed bracket 59. As the slide 11 begins to rise, at the completion of the driver stroke, the abutment 57 swings the lever 15 about its pivot, retracting the driver. The abutment 57 is of such size that it remains in contact with the lever 15 during the whole of the rearward movement of the slide 11.
